Abstract

Benign giant renal schwannoma is rarely found and the diagnosis difficulty only depends on physical and imagological examination. Pathological examination is essential to confirm the diagnosis of renal schwannoma. Nephrectomy and tumorectomy are primary treatments for renal schwannoma. Although most of the reported patients present satisfactory outcome, however, there is still not sufficient evidence to reveal the biological characteristics and post-operation recurrence rate of renal schwannoma. Herein, we report a rare case of giant and complicated renal schwannoma. A 56-years-old female patient was admitted to the urology department due to left lower back pain for approximately 5 days. No positive signs and other special abnormalities were found. CT scan presented a soft tissue tumor with inhomogeneous enhanced in the renal hilum. Surgery was performed to excise the tumor and left renal. Renal schwannoma was confirmed by pathological examination. At the 6-month follow-up, no evidence of recurrence was found. Our present report could provide more material for further study.

摘要

良性巨大肾神经鞘瘤很少发现，诊断难度仅取决于体格检查和影像学检查。病理检查对于确诊肾神经鞘瘤至关重要。肾切除术和肿瘤切除术是肾神经鞘瘤的主要治疗方法。尽管大多数报道的患者都呈现出令人满意的结果，但仍然没有足够的证据来揭示肾神经鞘瘤的生物学特征和术后复发率。在此，我们报告了一例罕见的巨型复杂肾神经鞘瘤病例。一名 56 岁女性患者因左腰痛约 5 天入院泌尿外科。未发现阳性体征及其他特殊异常。CT扫描呈软组织肿瘤，肾门不均匀强化。进行手术以切除肿瘤和左肾。病理检查证实为肾神经鞘瘤。在6个月的随访中，没有发现复发的证据。我们目前的报告可以为进一步研究提供更多材料。
